Title: Inverter device
Inventor: HIRAMATSU AKINORI
IPC: H02M1/42
Filed: 1990-12-24
Granted: 1995-10-17
Abstract: An inverter device has a full-wave rectifier providing a pulsating DC voltage from an input AC voltage, a smoothing circuit.  The smoothing circuit includes a choke coil, a smoothing capacitor and a switching element chopping the pulsating DC voltage through the choke coil into a smoothed DC voltage at the smoothing capacitor.  An inverter is included to have the element common to the smoothing circuit and operating to switch the smoothed DC voltage to apply a resulting voltage to a load circuit including a load, inductance and capacitor.  The inductance and capacitor define an oscillation circuit providing to the load an oscillating current composed of first and second currents of opposite directions.  The oscillating current alternating to flow for a nominal on-time duration determined by a circuit constant of the oscillation circuit itself.  A controller is included to detect the termination of the second current and excites the common switching element at a timing dependent upon the termination of the second current so as to start flowing the first current.  The controller includes a timer for separately controlling an actual on-time duration for flowing the first current within the nominal on-time duration, whereby enabling to regulate the accumulated DC voltage in the smoothing capacitor at a desired level by controlling to vary the actual on-time duration of the common switching element.

Abstract: A metal cutting drill with two replaceable cutting inserts which are positioned to cut the full circumference of a hole during each one-half revolution of the drill. Each insert is triangular and includes an active cutting edge having a curved corner to enable the insert to cut near the center of the hole. Each insert may be inverted and indexed in order to bring an alternately usable cutting edge into active cutting position. By virtue of the inserts being triangular, the curved corners on the cutting edges of the two inserts may be positioned relatively close together and yet sufficient space is left between the inserts to enable the drill body to be relatively thick and strong.

Granted: 2002-07-09
Abstract: A magnetohydrodynamic angular rate sensor is described. A housing (30) supports first and second fluid proof masses in respective coaxial annular channels (11, 17), permitting rela-tive motion between the proof masses and the housing. First and second magnets (12, 18) asso-ciated with each annular channel (11, 17) result in an electric potential being generated across each channel proportional to the relative circumferential velocity between the proof masses and the housing. The annular channels ace connected together to form a continuous pumped fluid circuit which introduces a radial flow velocity in each channel. At low rotational frequencies, a circumferential velocity component is induced in the proof masses due to Coriolis acceleration which results in a measurable electrical voltage across the annual channels.  The low frequency response of the sensor is therefor extended to lower frequencies.
